Stayed in a Deluxe Room in Dec. 2011 as part of a business trip to Japan. I've stayed here several times in the past, and it still looks like new and is squeaky clean to boot. Service is excellent (but then again, even 7 Eleven stores have great service in Japan), the rooms are comfortable and elegant and the lobby and restaurants scream "luxury."

It's about a 10 minute walk from the subway station to the hotel - good or bad, depending on your stamina. Be warned that during a heatwave during the Summer or the bitter cold of Winter every minute does add up.

While Tokyo has experienced a boom in high-class hotels in recent years (Mandarin Oriental, Ritz Carlton, The Peninsula, etc.), the Westin is a tad cheaper than the newcomers (still not inexpensive, however, and the strong yen is partly to blame) and is really the only choice if you're looking for top-class lodging in the Ebisu area.

I am staying roughly about 6 weeks a year at this propertly. And over the years since 2005 not much has changes. The property is being maintained greatly, you never have the impression anything is old. The rooms and bathrooms are very spacious and clean. The size of the room is the main reason i stay here. A generous 462 sqft or 42 sqm, this is a room size you do not find a lot in tokyo. In the mean time due to my regular stays as well as being a platinum spg i get quite often upgrade to a suite. The suite is lovely not too big just the right size and i love the bathroom.

Beside of that i have access to the Westin Executive Club which is spacious and well managed. I struggle still a bit with the food offerings which are in my opinion not much. Breakfast is adequate but nothing out of the ordinary. The restaurants at the Hotel in particular Victors and Yebisu are of high standard but very expensive.

Really depends what you looking for, but if you do not mind the price and expect 5-star ease and comfort, with 10 min walk away from JR station, it is everything that you need. Old school style is very personal, but at least it is a style. Perfect buffet. Good service. Room has everything you need. That's ease and comfort.

This Westin did not disappoint. Excellent rooms, comfy bed, stylish bathrooms with separate shower stall and good size tub. My room had a fantastic view of Mount Fuji.
Location is ok - 5 min walk from Ebisu station, which is not a major hub - good because it's less confusing for beginners in Japan, but getting to many places requires a connection. It is on the circle JR line though, so it is reasonably convenient.
Everything inside the hotel is very expensive - the breakfast buffet will run over $36 unless you prepay for the whole week, and bar drinks start from about $15 - but this is typical for Tokyo hotels.
Very good gym, machines with built in TVs, the weights area is a bit small.

The only disappoinment for me was that the hotel has very old-style design - marble inlay mosaic flowers, golden doorknobs, claw-foot chairs etc. Most Westins I stayed at have been real modern, clean lines and minimalistic - so this was a bit of a letdown for me personally. It does not take away from comfort of the hotel though. Great place to stay overall.
